TO WHOM IT MAY CONOERN: A K

Be it known that I, WILLIAM G. McGILL, of Cincinnati, Hamilton county,Ohio, have inventeda new and useful Lamp-Burner; and I hereby declarethe following to be a. full, clear, and exact description' of' the same,reference being vhad. to the accompanying drawings, making part of thisspecification.

My improvement relates to, first, a device for enabling the feeding ofthe lamp without detaching-either the burner or the chimney; secondly, aferm of Wick-tube by which the ase-ent of the oil in the upper part ofAthe wick is properly directed and accelerated; thirdly, a. form ofair-conductor which secures an eectual and copious draught; fourthly, animproved form of chimney-holder.

Figure l is an axial section through a lamp-burner embodying myimprovements.

Figure is a perspective view of the parts of the burner detached.

Figure 3 isaAside elevation of the burner in position for charging thelamp with oil.

' A represents the oil-receptacle, of customary construction, save thatits neck B, instead'cf the usual screwthread, has a smooth interior vtoreceive the smooth eyiindrical spring-stem C, having an opening, c, toadmit of its expansion into the neckA B, as well as to enable the .lampto he charged with oil, and an opening, c', to support the burner in theelevated position shown in fig. 3,'for the purpose of said chargingaction, without entirely detaching said burner. l

D is a collar, freely perforated vto admit dra ught-air, and having araised margin, d, to confine the airconductor E; and also to support onits outside periphery a nicely-fitted ring or ferrule, F, having two ormore elastic wings, f, that fit and expand into the` interior of thechimney, and a flange,j", at bottom to support the same. The chimney',being furnished with this ferrule, is secured `to its place on the lamphy being simply pressed over, so as to enclose theraiscd margin d of thecollar D, an interior flange,f, preventing the chimney being pushed' toofar down. l When it is desired to remove the chimney, the act isaccomplished by simply lifting of the same. l.

In arder to cause a frceand active upward draught, I form the conductorE with an upward are,1'so as to increase its capacity as the aircontained within it beeomeshotter, and thus to relieve thepressureandito facilitate the ascent of said air, thereby securing amore activedraught. i

i For the purpose of more rapidly andv Ieifeetually heating the oil asit aseends the wick, and of directing it to the proper points, I formthe upper edge of the \vicktube Gr into serrations g g g", whose points,entering thevilame, serve to conduct the heat downward and the'oilupward. The-central point g being in the hottest part of the flame,becomes effective to concentrate the upward flow of oil into said part,where it can be most p thoroughly consumed.

It' desired, the elastic wingsf may be permanently attached to thecollarl 'thus dispensing with a separate' ring, F, thechimney beingshipped and unshipped by drawing on' and off ef thetving's.

It will be seen that a burner provided with my elastic and perforatedtubular or hollow stem C, while very easily and quiekly'elevated forrefilling, does not require-to be ever wholly withdrawnfromthereservoir, and

that in its closedl condition it does not-necessitatcany unusual orinconvenient length of buruersor of wick, and

that it can be very cheaply and easily manufactured, dispensing entirelywith the use of the customary screw,

the elastic springs holding it in'place and insuring a tight joint.Ther-ing .F and the elastic wingsfmay, if

preferred, be permanently attach-ed to thc air-conductor E.

I'Ielaim herein as new, and -of m 'invention- 1. The elastic, tubular,and pel'forated stem C, substantially as described and shown, for' thevpurposes set forth. v

2.` The combination of the collar D, tube G, ring F,with elastic wings ff, all constructed and arranged substantially as shown, and for thepurposes/herein set forth.

v3z 'The conductor E, lformed and arranged as and for the purpose setforth.

21. The combination oi' the ring F and elastic wings ff andair-conductor E, when -constructed and arramgedA as herein shown anddescribed, and for the purposes heretoforeset forth.

In testimony of whichlinvention, I hercuntoset my hand.:
